CIRCULAR LQOM.

Application filed March 9, 1923. `serial No. 623,994.

T0 all whom t may concern.'

Be it known that I, Josnrrr STUER, a citizen of the United States, residing at Lawrence, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Circular Looms,

of which the following is a specification.

This invention relates to the weaving of cloth. It is a loom which wea-ves a circular tube of cloth having no selvage edges.

I am aware that tubes have been built up by a process of braiding, and that tubes have been built up by certain methods of crossing the threads to hold a filling, such as a paper ribbon, in place, but in my circular loom I weave aregular pieceof cloth where alternate warp threads cross in a regular manner.

I can also make fancy weaves on my loom, and can weave tubes 1of very large size and fine count.

The warp threads in my loom are delivered from warp carriers, such as spools, located in concentric circles, and lead to a. cloth tube. These warp carriers are moved in a manner which constitutes what might be known as a full floating warp without loops.

In the drawings, Figure 1 is a plan view of my loom with part of the frame broken away and only two of the filling arms shown in full lines.

Fig. 2 is a sectional elevation of diagrammatic form of the same loom shown in Fig. 1.

In the drawings, A represents the supporting frame asa whole resting on the floor 1.' This frame may be of cylindrical form extending upward at 2 which may be continuous or, preferably, of skeleton form, as is lalso the top 3, 3 which comprises, as shown, arms radiating inward to the ring 4 thereby suppor'tingthe interior cloth tube B which depends centrally therefrom. 10 is an exterior cloth tube supported by frame-C.

E represents an exterior ring shown as having gear teeth on the outside and 'an annular nose 40 which rests in an annular bearing 41 supported by frame A. This exterior ring E is revolnble in the frame A by means of a small driving gear. 32,-the teeth of which mesh with the tee-thon E. As shown, gear 32is carried by Va shaft 31 driven by the bevel gear l3*() and the bevel gear 29 carried by a suitable 4shaft 22 which,l through the medium of a clutch 21 `operated by a clutch handle 20, is driven by an electric motor D.

This shaft 22 through gears 23 revolves the take-up rollers 24 which take up the tube of cloth N as it comes from interior cloth tube B.

Two .or more filling arms F, F1, F2, are carried by the exterior ring E and project radially inward in substantially the same plane tothe cloth tube B. Each is provided with .a filling guide passage 5.9 through. which runs the filling G from the filling bobbins or filling carriers 44 and 45 supported on an annular shelf 43 carried by brackets 42 from ring E.

The filling G extends up through a suitable guide or hole 50 in each arm F, thence through the filling passage 59 and out through a filling finger 51 which projects to the cloth tube B. This filling finger, preferably, curves around kat 153 where it touches the cloth tube E and has a hole at 52 from which filling emerges, thence running through anotherhole and the ygroove 53 so that the curved part 153 of finger 51 serves the part of `a reed in beatingup filling between the warp threads 62 and 63.

Referring to the `diagram in Fig. 13, I iise fur warp. carriers, indicated by I-I,I H,

2 2 fil andrH1 are both operated-by the cams on a lling arm suoli as F, and H2, H2 on an adjoining filling arm. rlhese warp car riers are arranged in concentric rings inside exterior ring E and outside cloth tube B.

The principle of my machine is that when the outside warp carrier operated by any particular arm is raised, the corresponding one on the next linterior concentric ring is lowered, and at the sanietiin'e the 'adjoining arm ioweis'the "adjoining outside carrier and raises the corresponding lcarrier on the next interior concentric ring ofcarriers.

lt will therefore be seen that l require pairs of concentrically arranged 'carriers and'pairsot arms each of which has devicesv which operate to alternately rais'e and lower the carriers.

Referring to Fig. lll, this raising and lov:- eringfthe carriers H2 and H1 is clearly shown luy the course indicated bythe letters S, S,

and T, T, T, with reference to the filling arms lil and F1.

Referring new' to the principal drawings F l and 2, i3 represents an annular support standing up from the vbottom of the trame A, and l2 represents an annular support extending down from the top thereof. These" annular supports 1Q and 1.3 support series of pairs ot oppositely disposed concentrically arranged top and bottom warp carrier guides. The top carrierguides' are indicated "byll for'tlie outside 'and lil for Y the `inside,-aud 'the bottoni carrier guides by'- Lto'r the outside and'lr1 for the inside. 'lachotrthese carrier guides includes the loof; like supper-t or'Sl Withsuitable bearings for the'guide rods' 65, the outside ends of which are connected by bars 69.' VThe inside ends ofl' these rods are so vrformed as ,to maire a pocket (3el,'the' pockets o'i' the top guides adjoining 'those et the bottom:

lv sliowspringmeans (i6 which normally canse the top pockets Gil et said guides to nornia'lly rest in the 'same plane, which plane is' indicated in Fig; 4- by X, X.

"ln the sanenay` similar spring means cause the bottoni pockets 64- to normallyV rest' in :i parallel plane, such as indicated by Y, `vfin Fig. 4.'

The concentric rings oli warp carrier guides are indicated in Fig'. l bj: l@ and l. For each pair of oppositely disposed warp carrier guides, there is a warp carrier H, each of which registers with the pocket of a top and the pocket ot its corresponding liottoni warp carrier guide and cachot which, preferably, is'shown as having radially projecting shitting pins 67."

Each filling arm l? or F1 has two or moresets of Ycains llgone set arranged to engage the shiftingv pins on the outside ring of warp carriers so as to raise them, and another set so arranged as at the. saine time to depress the carriers on another ring.

iaoaeii rlhis is shown clearly in `Fig. 3 where the outside warp carrier H is depressed and the inside is raised.

On another, which may be the adjoining arm, is a plurality of setsof other cams, one set so arranged as to engage the shitting pins on the outside ring of warp carriers so as to lower itat the saine time that the adjoining arm is lifting another carrier ot the saine ring, and another set so arranged that at the same time it -will depress trie warp carrier on another ring while the iiistaneir tioned 4arm is raising another carrier of the same ring'.

ln a straight weave, as one arm goes around it lifts the outside warp carriers and depresses those of the inside, while the adjoining arm depresses the outside `and raises the inside. lt is obvious, however,that one or more arms might loe arranged tofliiit, and one or more other arms to depress, whereby various weaves and variouspat tei-ns could readily be Woven.

lt is also obvious that instead of two concentric rings of ywarp carriers with their guides, threey tour, er more might he used. is alsoolivious that with-my arrangement et rains and arms, a great many warp carriers can be arranged .in a circle and a ggreat'inany iilling arms canbe continually lilling in so that ,o ljreat speed ot production ca' lie obtained. f

lin l`ig.- d, l showv diamond-shaped cams 5l the of one being` at such point that it will strilce under the pins 67, and et others so that they will strike over those pins. Itv is also apparent thatA the cams are so arranged vthat while Aforcing down the warp carriers the same cani is forcing, up the warp guides so as to allow a larger space tor the yarms, such as F as shown in Fig. Il. this arrangement, greater height-and therefore more strength can-loe given each arm lf, and this is a practical advantage However. as shown in l0, l may use a plough-shaped cani 9i l 7ing nose 95 arranged in one case to pass under, and in another case over pins GT. The tace 93 is the practical working tace, the back end 94 ini-rely allowing the pins with their carriers-to slide down easily without banging. The other 'faces of these cams are shown as i noperative.

is shown in Figs. 1l and l2, the shitting )ins (3T can be omitted and cams such as 'tll positioned to stril-:e over the middle oi cach warp carrier H can be used.

-ln this case the arni F must be of suoli size that it will pass betweenthe planes indicated by X, X and Y, Y -,which indicate the limits ot the movements vtowardsgeach other ot the pocketsfory thewarp carriers, and each arin `must have room enough to project up and down so that its end 101 will reach over or under a Warp carrier H.

The adjoining cam 102 is the same as 100 With an end 103 which extends under the Warp carrier H instead of over it.

As shown in Fig. 15 the pockets at the ends of the guide rods may be continuous, as shown at 110.

As shown diagrammatically in Fig. 16, instead of' bobbins such as 44 and 45, or spools 'for carrying the filling, or spools such as 82 for carrying the Warp 63 or 62, as shown in Fig. 8, I may use a skein indicated by 115 or any other similar device.

As a practical matter, I may arrange my filling as shown in Fig. 9, wherein 43 is the shelf' and 44, 45 and 45A the series of bobbins arranged thereon, preferably, on suitable spindles, not shown. l

The free end from the first bobbin 44 indicated by 73 is passed up through a ring 70, thence to the filling arm, and its other end 74 is passed up through the ring 70 thence down through another ring 71 Where it connects with the outside end 75 from the next bobbin 45. The inside end 76 from this bobbin extends up through a ring 71 thence down through a ring 72 Where it connects with the free end 77 of bobbin 45A, and so on. This arrangement permits a number of small bobbins of usual size to be used for the filling.

As my filling finger 51 directs the filling into the extreme angle of the shed, and as the threads of the Warp are almost instantly crossed, after it has passed no reed is necessary and it is impossible to form kinks.

I may use an interior cloth tube B and an exterior cloth tube 10 or either of them, according to the nature of the Work.

In any case I find it desirable to use cloth spreaders 2T, 2T to flatten out the tube of cloth before it is Wound up.
